The pylorus contracts to slow gastric emptying and results in
further mixing of gastric contents. During this time, the stomach
transforms its contents into multiphase slurry called chyme, which
is a combination of separate phases of aqueous solutions, fats, and
solids. The more intense peristaltic waves promote antral empty-
ing, which allows gastric contents, mainly fluid mixed with small
particles, to pass through the pylorus and enter the duodenum. The
particle size of the food emptied through the pylorus is less than 1
to 2 mm during the fed state (Thomas 2006).
